Abstract
The present invention is intended to provide a kind of outstanding pouch-shaped high vertical sediment trapping net fixes the construction method of moving dunes, belong to sand control engineering technical field；Purpose is the defect for overcoming prior art, the structure of existing high vertical sediment trapping net, such as curtain is hung from single width, change over the outstanding pouch-shaped high vertical sediment trapping net of the mesh bag shape that bag bottom is hung up equipped with Desert Sand, the bottom that sediment trapping net has front wire side and rear wire side, net is made to have sand drift to suppress, sediment trapping net will not be blown down from the base erosion of net by strong wind, outstanding pouch-shaped high vertical sediment trapping net is constructed at the top of moving dunes, the purpose of fixed moving dunes is reached.
Description
Technical field
The present invention relates to sand control engineering technical field, specially hangs the construction that pouch-shaped high vertical sediment trapping net fixes moving dunes
Method.
Background technology
At present, in desert treatment, plastic wire construction high vertical sediment trapping net is widely used, is implemented to desert of flowing
Intercept and fixed, but above-mentioned high vertical sediment trapping net due to vertical wire side, when being attacked by strong wind, not only wire side is easily blown
Broken, the wind being blocked changes over upper and lower vertical direction from horizontal direction, the sand of wind meeting erosion sediment trapping sieve bottom vertically downward, makes
Sediment trapping sieve bottom is hanging, constructs just very unstable at the top of moving dunes and check dam, therefore invents a kind of outstanding pouch-shaped Gao Li
Formula sediment trapping net is fixing the needs that moving dunes have been control of desert.
Applicant was delivered in 2009《The fixation and utilization of moving dunes》, splayed cylinder mould is illustrated in article husky
The principle of the fixed moving dunes of barrier, while illustrating at the top of moving dunes after setting splayed net cage sand barrier, due to Sha Wanggao
The characteristic of place's stream, tall and big moving dunes have reformed into tall and big mechanical sand barrier, therefore the mechanical sand barrier resistance of textbook husky public
Formula V=4.5H2Sina (formula 1), is modified as V=4.5H2+[H1+H2]2Sina (formula 2)；In (formula 1), V is mechanical sand barrier
Height, a is the angle of cut.In (formula 2), V is measured for resistance is husky, height of the H for mechanical sand barrier, height of the H1 for moving dunes windward slope,
Height of the H2 for moving dunes leeward slope, a is the angle of cut.As the top that splayed net cage sand barrier exposes moving dunes is less than
15cm, if applying mechanically the formula on textbook, the splayed net cage sand barrier being placed at the top of moving dunes, the husky effect of resistance be it is micro- its
It is micro-, but actually expose the splayed net cage sand barrier of top of sand dune hillock 15cm, due to there is the flowing under cylinder mould sand barrier husky
Liner is made on mound, and the husky effect of its resistance is significantly larger than arranged on high vertical sediment trapping net on flat desert, highly more than 150cm.Cause
This (formula 1) is not applied to the husky effect of splayed net cage sand barrier resistance at the top of moving dunes of constructing, it is necessary to use (formula 2) ability
Describe the problem.After at the top of moving dunes, splayed net cage sand barrier is set, the sand drift intercepted by splayed net cage sand barrier
Product makes lifting upwards at the top of moving dunes in top of sand dune by lifting splayed net cage sand barrier, and moving dunes are just not further along
Mobile, harmful moving dunes reform into beneficial mechanical sand barrier, and the mechanical sand barrier of such height is built with any method
High vertical sediment trapping net cannot be accomplished, so as to show the function in the efficient intercepting desert of moving dunes.But on desert
The mechanical sand barrier being so efficiently easy to get, it is also not recognized at present, fail so far correlation theory and reality are found in textbook
Certification of registered capital material.What is introduced on textbook is the waist for high vertical sediment trapping net being arranged on moving dunes, reaches and scabbles moving dunes
Purpose, so far people still using moving dunes as disaster processing, so applicant trying by engineering practice, come
Prove that moving dunes can be to be transformed into tall and big mechanical sand barrier.
The construction method of outstanding pouch-shaped high vertical sediment trapping net fixation moving dunes is applicant from construction splayed net cage sand barrier
The construction method for exploring out in the engineering practice of fixed moving dunes, the bottom for hanging pouch-shaped high vertical sediment trapping net is to be loaded with sand
Bag bottom, it is more stable than splayed net cage sand barrier, can highly exceed splayed net cage sand barrier, therefore sediment trapping effect is than splayed net
Cage sand-protecting barrier is good.
The content of the invention
The technical problem to be solved in the present invention and the technical assignment for proposing are to overcome existing technological deficiency, existing height
The constructing structure of vertical sediment trapping net, hangs such as curtain from single width, changes over the mesh bag shape that bag bottom is hung up equipped with Desert Sand
Outstanding pouch-shaped high vertical sediment trapping net, make sediment trapping net that there is front wire side and rear wire side, can desert drift sand intercept in outstanding pouch-shaped Gao Li
Both sides in front and back between two faces of formula sediment trapping net with sediment trapping net.
Sediment trapping net of the present invention is plastics of the porosity between 45% to 55% between wide cut 120cm to 350cm
Net.
Outstanding pouch-shaped high vertical sediment trapping net fixes the construction method of moving dunes, it is characterised in that：The dune ridge of moving dunes
Line elapses 1m to 10m to windward slope direction from leeward slope side, and heap erects high 20cm to 50cm upper flats into wide 50cm extremely
The husky ridge of 200cm platforms, digs a bar ditch on husky ridge platform, the width of ditch between 30cm to 70ccm, depth in 15cm extremely
Between 50cm；Sediment trapping net of the wide cut between 120cm to 350cm is selected according to the width and depth of ditch, sediment trapping net along ditch
Spread out and put on, the center line of sediment trapping net is corresponding with the center line of bottom of trench, batten of the length between 70cm to 230cm is taken by sediment trapping net
Press-in bottom of trench, batten are inserted after vertically piercing through sediment trapping net in the sand of bottom of trench, and the depth in batten insertion sand is in 30cm to 70cm
Between, batten is fixed in ditch, becomes the support of outstanding pouch-shaped high vertical sediment trapping net, in the ditch for having spread out and put on sediment trapping net, interval
1m to 2m one support of construction, one by one between support, connection is tightened by an iron wire in top, to strengthen support left and right directions
Stability, take near Desert Sand be pressed in sediment trapping on the net ditch filled up, then the sediment trapping net of ditch both sides is propped up upwards, is tightened,
The top margin tendency cradle top of sediment trapping net is simultaneously fixed with cradle top connection, then be spaced tops of the 30cm to 50cm both sides sediment trapping net
Side and iron wire are coupled to be fixed, and constitutes outstanding pouch-shaped high vertical sediment trapping net, and so outstanding pouch-shaped of dune ridge line construction along moving dunes is high
Vertical sediment trapping net.
Outstanding pouch-shaped high vertical sediment trapping net changes the structure of traditional high vertical sediment trapping net, makes sediment trapping net inclined with two
Wire side, can intercept desert drift sand the both sides in front and back for being fixed in the middle of two wire sides of outstanding pouch-shaped high vertical sediment trapping net and netting, by
It is to be loaded with husky mesh bag bottom in the bottom of sediment trapping net, strong wind can not produce erosion to the base of sediment trapping net, be especially suitable for construction
At the top of the most powerful moving dunes of wind-force.
